android – 修复Google-Map中两个Marker之间的缩放级别

LatLngBounds.builder builder = new LatLngBounds.builder();
    builder.include(origin);
    builder.include(dest);
    LatLngBounds bounds = builder.build();

    Cameraupdate cu = CameraupdateFactory.newLatLngBounds(bounds,50);
    mMap.animateCamera(cu);

您正在使用正确的代码,如果您想要缩小(外部)或减少到0,如果您想要在包含两个标记的最小区域中,则需要增加值(50)(您可以跳过该值如果).

如果设置值为150或更高,并且级别太高,则可以使用动画回调在“latlng”缩放后缩小：

https://developers.google.com/android/reference/com/google/android/gms/maps/GoogleMap.html#animateCamera(com.google.android.gms.maps.CameraUpdate,com.google.android.gms.maps.GoogleMap.CancelableCallBACk)

LatLngBounds.builder builder = new LatLngBounds.builder();
builder.include(origin);
builder.include(dest);
LatLngBounds bounds = builder.build();

Cameraupdate cu = CameraupdateFactory.newLatLngBounds(bounds,50);
mMap.animateCamera(cu,new GoogleMap.CancelableCallBACk(){
    void onCancel(){}
    void onFinish(){
        Cameraupdate zout = CameraupdateFactory.zoomBy(-3.0);
        mMap.animateCamera(zout);
    }
});

这应该缩放到latLng,完成后,缩放3级.
